# 181. 超过经理收入的员工

![在这里插入图片描述](https://img-blog.csdnimg.cn/20190429160126587.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2phY2tpZV9vMm8y,size_16,color_FFFFFF,t_70)

```sql
# Write your MySQL query statement below
select a.Name as 'Employee'
from Employee as a,Employee as b
where a.ManagerId=b.Id
        and a.Salary>b.Salary;

```

1.employee的表出现了两次，分别命名为a，b，因为只有一个表要使用两次，为了避免二义性才用不同的名字\
2.注意结果那里显示的列名是：Employee而原表是 Name
